Description
- This invention relates to apparatus for measuring impact sound insulation provided by a shared dividing structure comprising a floor of a first room of a building and a ceiling of a second room of the building.
- Apparatus is known which is for measuring impact sound insulation provided by a shared dividing structure comprising a floor of a first room of a building and a ceiling of a second room of the building. The known apparatus comprises a tapping machine for generating a tapping sound in the first room of the building. The known apparatus also comprises sound measuring means for measuring the level of the sound in the second room in the building, with the second room being underneath the first room and such that the first and second rooms form a room pair with the shared dividing structure comprising the floor of the first room and the ceiling of the second room. The known apparatus also comprises mounting means for mounting the tapping machine on the floor of the first room.
- In order to obtain meaningful measurements, the tapping machine has to be operated in a plurality of random positions on the floor of the first room of the building. Current regulations in the United Kingdom require the tapping machine to be operated in at least four random positions on the floor of the first room of the building. The requirement for random positioning of the tapping machine on the floor of the first room of the building typically requires the apparatus to be operated by two persons. A first person randomly positions and operates the tapping machine in the first room of the building, and a second person operates the sound measuring means in the second room of, the building. The requirement for two persons is often not convenient in that only one person may be available. In addition, the requirement for two persons typically costs double what it would cost for one person.
- Sometimes the known apparatus is operated by one person. In this case, the person has to keep moving between the first and the second rooms in order to position and set up the tapping machine at a required random position in the first room, and then walk to the second room to operate a remote controlled 'on' switch and the sound measuring means. Often the first and second rooms in a room pair are not conveniently accessible and it may be necessary for the person to walk a considerable distance in order to gain access to the first and the second rooms. In addition to being frustrating and tiring, the time taken to walk between the first and the second rooms may cause time costs to be similar to the time costs of employing two persons.
- It is an aim of the present invention to avoid or reduce the above mentioned problem.

- The apparatus of the present invention is advantageous in that it is able to be operated by one person. This avoids the above mentioned problem with the known apparatus when it is operated by two persons. The apparatus of the present invention also avoids the above mentioned problem with the known apparatus when it is operated by a single person. With the apparatus of the present invention, a single person in the second room of the room pair is able to operate the tapping machine in the first room of the room pair, this being done by using the remote control means to control the mover means to cause the tapping machine to move to required random positions over the floor of the first room.
- The apparatus of the present invention may be one in which the mounting means is a part of the tapping machine. Additionally or alternatively the mover means may be a part of the tapping machine.
- If desired, the apparatus of the present invention may include a cradle for the tapping machine.
- When the apparatus of the present invention includes a cradle for the tapping machine, then the mounting means may be a part of the cradle. Additionally or alternatively, the mover means may be a part of the cradle.
Generally, when the cradle is employed, then one or more parts of the apparatus that would normally be on the mounting means may instead be on the cradle. - In all embodiments of the present invention, the mounting means may comprise a plurality of feet. These may be four feet, for example one at each of four corners of the tapping machine. More or less than four feet may be employed. If desired, the mounting means may be a central elongate mounting structure rather than a plurality of feet.
- The mover means may comprise wheels for enabling the apparatus to be movable over the floor of the first room. The wheels may be Mecanum wheels, Universal wheels or plain wheels. The Mecanum wheels enable the apparatus to be moved forwards and backwards, and at various angles in a horizontal plane.
- Alternatively, the mover means may comprise endless tracks for enabling the apparatus to be movable over the floor of the first room. Other types of mover means may be employed.
- In the invention, the apparatus includes a lowering and raising means for causing the mounting means to be lowered to a first position in which the mounting means contacts the floor of the first room when measurement of the level of the sound in the second room is to take place, and to be raised to a second position in which the mounting means does not contact the floor of the first room when movement of the tapping machine over the floor of the first room is to take place.
- The lowering and raising means may be a part of the tapping machine.
- Alternatively, the lowering and raising means may be a part of the cradle. Alternatively, the lowering and raising means may be another part of the apparatus.
- The lowering and raising means may comprise meshing gear teeth or a cam arrangement. Other types of lowering and raising means may be employed.
- The remote control means may include a processor which is programmed with random positions for the tapping machine on the floor of the first room.
- Additionally, or alternatively, the remote control means may comprise a screen with X and Y co-ordinates for use in moving the tapping machine to random positions on the floor of the first room. Currently the tapping machine needs to be moved to at least four random positions in order to comply with current United Kingdom regulations. The tapping machine could however be moved to more or less random positions in dependence on other requirements, for example regulations in other countries.
- The apparatus may be one in which the remote control means is a part of a mobile telephone, and in which the control means is then in the form of an App. on the mobile telephone. Alternatively, the control means may be a dedicated control means. The dedicated control means would then only be for use in operating the tapping machine.
- The apparatus may include a camera for enabling the person to see a view from the tapping machine when the tapping machine is in the first room and the person is in the second room. The camera may be mounted on the tapping machine. The camera may be mounted elsewhere if desired, for example on the cradle if a cradle is employed.

The mover means 38 are mounted on thecradle 52 as shown. - It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, different types of tapping
machines 6, sound measuring means 10 and mounting means 22 may be employed. Only one of the mounting means 22 and the mover means 38 could be on thecradle 48, with the other one of the mounting means 22 and the mover means 38 being on the tappingmachine 6. Thewheels 44 may alternatively be wheels of other configurations, or casters or rollers. Theapparatus floor 18 of thefirst room 8 when measurement of the level of sound in thesecond room 12 is to take place, and to be raised to a second position in which the mounting means 22 does not contact thefloor 18 of thefirst room 8 when movement of the tappingmachine 6 over thefloor 18 of thefirst room 8 is to take place. The lowering and raising means may be a part of the tappingmachine 6 or part of thecradle 48. Any suitable and appropriate type of lowering and raising means may be employed, for example a lowering and raising means comprising meshing gear teeth or a cam arrangement. - The tapping
machine 6 may be operated by one or more batteries and/or mains electricity. The tappingmachine 6 may be fitted with sensors which are capable of sensing the proximity of the tappingmachine 6 to room boundaries or other objects within thefirst room 8. This allows confidence on the part of the person that each test position for the tappingmachine 6 complies with official requirements which may include, for example, a minimum distance from floor boundaries of 0.5metres. The tappingmachine 6 and/or a processor in the remote control means 40 and any coupled devices may also transmit images to theperson 34 so that theperson 34 can see where in thefirst room 8 the tappingmachine 6 is actually situated at any one time.
